Abstract
We report the observation of heavy-fermion superconductivity in CeCoIn5 at T-c = 2.3 K. When compared to the pressure-induced T-c of its cubic relativ e CeIn3 (T-c similar to 200 mK), the T-c of CeCoIn5 is remarkably high. We suggest that this difference may arise from magnetically mediated supercond uctivity in the layered crystal structure of CeCoIn5.
